Where can I find my electricity MPAN?
Your MPAN is on your electricity or dual fuel bill, usually in a box marked ‘Supply Number’. It’s 21 digits long and begins with ’S’. You’ll only need the last 12 or 13 digits. You won’t find your property’s MPAN on your meter box.
Don’t confuse it with your customer reference number, which can also be found on the bill.
